The National Security and Defense Council of Ukraine instructed the Security Service of Ukraine to clarify the circumstances of the ratification of the Kharkiv agreements of 2010 on the conditions for the stay of the Russian Black Sea Fleet in Crimea. This was stated by the secretary of the National Security and Defense Council Alexei Danilov, stressing that the SBU should find out how 236 deputies of the Verkhovna Rada voted on this issue. He stressed that, if necessary, a criminal case on high treason can be initiated against parliamentarians.. Danilov explained that the vote for the Kharkiv agreements took place suspiciously quickly - four days after their signing..

As a result, according to the NSDC secretary, this led to the fact that Ukraine lost Crimea and received a conflict in Donbass.. On April 21, 2010 in Kharkiv, representatives of Moscow and Kiev signed an agreement that the stay of the Russian Black Sea Fleet was extended by 25 years in exchange for a reduction in the price of Russian gas by 30%, but not more than $ 100 per thousand cubic meters. On April 27, 2010, deputies of the Verkhovna Rada ratified the document.
